LTO drive microcode may be a factor in this. (See IBM site Readme http://www-1.ibm.com/support/docview.wss?uid=ssg1S1002360 for a summary of microcode levels.) You didn't mention your environment, but the 1117 "errno" would be a Windows System Error number (rather than a Unix errno). There may be further details of value in your Windows Event Log to try to get any specifics, as the messages don't tell you anything much beyond there being an I/O error.
